CD4 and neoplasm: As for GGT5 (Figure 7B), expression of GGT5 was strongly correlated with tumor purity (r = −0.526, P = 5.39e-26) and positively associated with infiltration of CD8+ T cells (r = 0.193, P = 3.36e-4), CD4+ T cells (r = 0.352, P=1.85e-11), macrophages (r = 0.304, P = 9.57e-9), neutrophils (r = 0.213, P = 6.45e-5), and dendritic cells (r = 0.212, P = 7.935e-5).
